var a = document.getElementsByTagName("a");
//alert(a.innerHTML);
// Code is for the <environment>. This part is to hide the related information title
if (document.getElementById("apptab_AAPA-P9439N"))
{
document.getElementById("apptab_AAPA-P9439N").innerHTML = "";
document.getElementById("apptab_AAPA-P9439N").innerText = "";
}

</script>

The button gets renamed, but I want the related info tab to be hidden or with no text.
Any help / advice.
